PULSATING HEAT PIPE PYRAMIDAL SOLAR STILL

. Water is the most essential need for everyone sometimes not available to all. Many remote and hilly area suffer water scarcity in daily life. Solar desalination is one of the techniques for achieving this common goal of freshwater yield. This study delves into the integration of pyramidal solar stills coupled with pulsating heat pipes (PHP) to maximize heat transfer and enhance overall system performance in solar desalination. System components and factors affecting productivity, including water depth, insulation, cover inclination and innovative designs, are thoroughly investigated. The experiment focused on comparing the performance of two types of solar stills. The conventional pyramid solar still (CPSS) and the modified pyramid solar still (MPSS) integrated with a pulsating heat pipe (PHP). The study evaluated their efficiency in freshwater production, energy utilization and economic feasibility. The MPSS’s superior performance in freshwater yield, hourly productivity and thermal efficiency across varied water depths
